INTRODUCTION
The Ducted Slim models are R-410A fan coils designed with 
application flexibility in mind. The 9K-48K sizes can be 
mounted horizontally or vertically (upflow) while the 58K size 
can be mounted only horizontally.
A rear and bottom return is available for field modification on 
the 9K-48K sizes to match the different applications.
All these fan coils have a DC fan motor with variable speeds 
for efficiency and comfort. The static pressure can be manually 
set up or use the constant air volume control.
The ducted fan coil unit is shipped with a condensate lift pump 
providing a maximum lift of 29.5in (750mm).
ACCESSORIES
The system is shipped with the following accessories. Use all
of the installation parts and accessories to install the system.
Improper installation may result in water leakage, electrical
shock and fire, or cause the equipment to fail. Keep the
installation manual in a safe place and do not discard any other
accessories until the installation work has been completed.

NOTES: 
- If the outdoor unit is higher than the indoor unit, prevent rain 
from flowing into the indoor unit along the connection pipe by 
creating a downward arc in the connection pipe before it 
enters the wall and enters the indoor unit. Doing so helps 
ensure rain drips from the connection pipe before it enters the 
wall.
- Piping and the interconnecting wiring are field supplied.
- Fig. 3 is a sketch. Different models may differ slightly.
